What the AI looks for in Automotive Replacement Ignition Starter Switches

Separate from the lock
Confirm whether the electrical switch is separate from the lock cylinder. On many GM columns it sits lower and is moved by an actuator rod. You may only need one part, not both.
Terminal count and connector
Match the pin layout and connector shape exactly Starter, accessory, run and ignition circuits vary by platform.
Column type
Match tilt or fixed column, and automatic or manual transmission Mounting and actuator geometry differ between column types.
Adjustment
Set the switch position to the service procedure on actuator-rod designs A misaligned switch causes no-crank or accessory faults.
Connector condition
Inspect the connector for heat damage and replace it if melted High current through a bad connection burns new switches quickly.

Questions

Is it the starter or the ignition switch?

If the dash lights and accessories work in the run position but there's no voltage at the starter signal wire in the start position, the switch or the safety circuit is at fault. If voltage is present, look at the starter or relay.
